Chapter 19, Problem 19.24P
Interpretation Introduction

(a)

Interpretation:

The cis/trans ratio refers to in permethrin is to be predicted.

Concept Introduction:

Permethrin is a synthetic insecticide containing ester group. They are used in commercial clothing and agricultural products. In cis-isomer, the atom or groups linked to the ring are on the same side of the ring or double bond. In trans-isomer, the atom or groups linked to a ring are on the opposite sides of the ring or double bond.

Interpretation Introduction

(b)

Interpretation:

The (+/) designation in cis / trans ratio refers to in permethrin is to be predicted.

Concept Introduction:

Permethrin is a synthetic insecticide containing ester group. They are used in commercial clothing and agricultural products. Racemic mixture is a mixture of enantiomers in equal amounts. It is optically inactive.

For each of the following statements, indicate whether they are true or false and, in the second case, correct them appropriately: a) In biological systems, copper is often found in the form of blue proteins, so called because they absorb light from 450 to 500 nm b) Aldehyde oxide reductase is a copper enzyme that oxidizes aldehydes to carboxylic acids c) The only metal that carries oxygen transport in living beings is iron d) Superoxide dismutase catalyzes the decomposition of the anion superoxide in water and hydrogen peroxide e) Holochromodulin is activated when insulin levels decrease, binding to its receptors. f) Ferredoxins are metalloproteins present in the liver of all animals, whose purpose is to store iron
As part of an investigation on Pb in biological ecosystems, some grasses that grew along the road and were exposed to emissions from motor gasoline were collected. 6.2501 g of grass were calcined to destroy all organic matter, the inorganic residue was properly treated and finally made up to 100 mL. An aliquot of 50 mL of this solution was read in an atomic absorption spectrophotometer registering an absorbance of 0.1250; then 0.10 mL of a standard solution of 55 µg of Pb / mL were added to the other 50 mL, with this fortified sample, another absorbance measurement was made, which was 0.1798. Calculate the µg of Pb / g of grass
